EM720

The EM720 series is a group of state-of-art multi-microprocessor-based digital instruments that incorporate the capabilities of a power quality analyzer, energy meter, fault and data recorder and programmable controller, oriented for substation, industrial and commercial areas. These instruments provide three-phase measurements of electrical quantities in power distribution systems, monitoring external events, operating external equipment via relay contacts, fast and long-term on-board recording of measured quantities, transient voltages measurements up to 2KV, fault recording of currents up to 50A, harmonic analysis and disturbance recording. The expertmeter EM720 is an electronic revenue accuracy multi-rate polyphase static meter integrated with a multi-function powermeter, an EN50160 power quality recorder, a digital fault recorder and a programmable logical controller, and provided with a wide range of digital I/O and communication options. A high-contrast graphical LCD display with backlight allows easy local meter readings and servicing. Two serial communication ports (infrared and RS232/RS485), a USB port, Ethernet and a wireless GSM/GPRS modem allow local and remote automatic meter readings and setup though the supplemental communication software or user data acquisition software.

The EM720 uses flash memory for storage device firmware that allows future (upgradation) of the device without replacing any hardware component. The new features can be easily added to your device by simply replacing the firmware through a local RS-232/RS-485, USB port or Ethernet port.
